I purchased this item 25-30 yrs ago because it made me smile. The dealer that sold it had no information on the maker nor the function. It is handmade in heavy gauge copper. There is a tube holder in the back and holes in the ears for earrings. It is signed on the bottom PDW and a design? number. The only company I could find is Portland Design Works that make bicycle accessories.
It is fairly large at 9 1/2" tall and the face around 9". In good vintage condition & probably dates 1970-80s. Great piece for displays.
